Ok. Next question is what did the structure weigh when it fell? Including all of the furnishings of the tenants?

Sure approx 96,000 tons of steel and about 80-90,000 tons of concrete for the floor slabs in each tower add in services ie pipework, cables, h&v, glazing and cladding it works out at about 220-235,000 tons in each tower.
Thanks for your reply. This link says 1,500,000 is the weight (of the two?) towers. Others say 500,000 tons each. Morgan Reynolds says 1,000,000.

Most of the 1,000,000 plus guesstimates are based on info regarding the cubic mtrs of concrete delivered to the site BUT that included things like the BATHTUB which is not part of the buildings also the floorslabs had a less dense mix of concrete than say would be used for a structural mix so the 220-235,000 ton estimates will be more accurate.

WHY? it would be a LOW percentage of the total weight!

The wtc towers wave lasted 8 or 9 seconds. One would expect the towers to last longer as they fell from a much greater height.
At the time, construction throughout the region was 100% controlled by organized crime. There were many interviews with construction workers (identities kept secret) at the time, complaining of the steel not being up to standards, shoddy welds being approved,
also find how much infil was taken in ?? to the site taken in

Find out how much debris was hauled away - you will then have the weight of the buildings and furnishings!
Each of the Twin Towers totally collapsed in intervals of approximately 14 to 16 seconds.

Each of the Twin Towers totally collapsed in intervals of approximately 14 to 16 seconds.
Free fall time from the same height, for any freely dropped object in nothing but air, is, just over 10 seconds, even closer to 10.5 depending on shape of the object in question, whether a large steel safe or a grand piano or a car or whatever.
Which leaves, for every welt and bolt to snap, from the impact levels, to the ground, what - 4-6 seconds?
Giant steel building - one, two, three, four. (break break break break). Down.

slowed only marginally by the thousands of almost instantaneous structural overloads that take place all the way down.

Skep, with all do respect.

If these guys
knew they were being tossed under the bus like this? They would freak the #### out. I've worked high rise
structural iron go'in on 20 years. I'm here to tell you shoddy welds absolutely do not happen. It's the most ungodly absurd thing I've ever heard of. Hello ! Iron workers themselves will take out and grind a weld and redo it without it being inspected. In fact it can be said that there are no better structural inspectors than the iron workers them selves. Doesn't matter what organized crime boss is do'in any where at any time? Because the ironworkers lives depend on it before any one elses. The only welds that really get inspected
are the ones that hold down the deck til the concrete gets poured. To say the iron work on WTC was shoddy?
Negative !

So that we can compare the twin towers with a known controlled demolition.
The Seattle King dome was 125,000 tons. When it collapsed due to controlled demolition it registered like a 2.3 earth quake. Compare this with the twin towers. If theirs was a controlled demolition one would expect a larger seismic number. It did not happen.
Furthermore, the twin towers produced only a single surface (seismic) wave unlike the King dome that produced the usual family of waves we see in an earth quake.
Also, the King dome collapse lasted 16.8 seconds. The wtc towers (seismic) wave lasted 8 or 9 seconds. One would expect the towers to last longer as they fell from a much greater height.
The King dome produced a dust cloud that was gone after 20 minutes.
The King dome produced a pile of rubble about 12% of the original height. The WTC rubble was about 4%. The volume of the towers was many times that of the King dome. Where is the rubble?edit on 3-12-2013 by leostokes because: (no reason given)edit on 3-12-2013 by leostokes because: (no reason given)
I agree with you.
Can airplanes dissolve into steel buildings as seen in all footage, in your opinion?
